U-KISS Dongho appeared as the youngest guest MC for MBC "Quiz That Changes The World."

Dongho was the special MC for the Saturday episode of "Quiz That Changes The World."

The episode featured other guests like Hyun Mi, Cho Chun, Seo Su Nam, Kim Han Guk and Park Hyun Bin. Singer Hyun Mi, for whom this year is her 55th year since her debut, was a staggering 56 years older than Dongho. Because of the older guests on the show, the normally oldest Sunwoo Yong Yeo became one of the younger ones on the show.

Dongho said, "There are so many older and more experienced singers here, which is scary. I did prepare something and brought gifts," and revealed boxes of dolls and roses. 

Thoughout the episode, he had a hard time catching up to the guests and panel's witty and fast talk. He was fanning his ever blushing face and this made everyone laugh.

Park Hyun Bin received a New Artist award in Japan, with his trademark song, "Bling Bling."
